Button mushrooms are characterized by their small size, with caps typically ranging from 1 to 3 inches in diameter. The cap color can vary from white to light brown, depending on the maturity of the mushroom. The stem is short and thick, and both the cap and stem have a fleshy texture.
Cultivation of Button Mushrooms
Growing Conditions required
Button mushrooms require specific growing conditions to thrive. They are typically cultivated indoors in controlled environments called mushroom houses or mushroom beds. The ideal temperature for growing button mushrooms ranges between 55 to 65°F (12 to 18°C), with a humidity level of around 85%. The growing medium, known as the substrate, plays a crucial role in cultivating button mushrooms. Common substrates include compost, straw, and manure, which provide the necessary nutrients for the mushrooms to grow.
Steps involved in Cultivation
The cultivation of button mushrooms involves several steps. First, the substrate is prepared by composting and pasteurizing it to eliminate any potential competing organisms. Then, the mushroom spawn, which is a mixture of mycelium (the vegetative part of the fungus) and a carrier material, is added to the substrate. The spawn acts as the inoculum, introducing the desired mushroom culture to the substrate. The beds are then placed in a controlled environment and covered with a layer of casing soil, which helps regulate moisture levels. The mushrooms are typically ready to harvest within 3 to 4 weeks after spawning.
Harvesting and Storing
Button mushrooms are typically harvested when the caps are tightly closed and before the gills underneath the cap start to darken. To harvest, the mushrooms are gently twisted or cut at the base of the stem. It is important to handle the mushrooms delicately to avoid damaging the fragile caps. After harvesting, button mushrooms can be stored in a refrigerator for up to a week, although they are best consumed fresh for optimal flavor and texture.
